Calculation of Helical Gear Meshing Efficiency

The instantaneous meshing efficiency of helical gears is defined as: Where, Tp and Tg are the torque of main and driven wheels respectively, N · mm. If the rolling friction between meshing tooth surfaces is ignored and only sliding friction is considered, the instantaneous meshing efficiency of helical gears...

Spur gear meshing impact excitation

Ideally, the meshing form of spur gear pair is shown in Figure 1. It can be seen that one end of the gear teeth is “perfectly engaged”, and the other end has a certain gap due to the existence of backlash. However, due to errors, time-varying meshing stiffness and...
